Hello folks,

I have a question about the interpretation of my point cloud data. Actually, everything is clear to me, but I don't really understand the values in data[] itself. I have understood that these numbers are represented in 4 byte values (uint8 FLOAT32 = 7), so for example 128 = 00000000 00000000 00000000 10000000.

example snippet: [128, 63, 188, 116, 147, 65, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 128, 63, 80, 141, 151, 65]

he question is what every 4 values represent:

   x = 128
    y = 63
    z = 188
    intensity = 116

or am I wrong and x = 128,63,188,116.

Additional question: Thank you both, I could get the information I've searched. Only one thing, if its mentioned, that the bytes are stored in little endian. It must be stored like this 128,63,188,116 for x:

memory a: 128 a+1: 63 a+2: 188 a+3: 116

or will it be stored from the right side beginning, so:

memory a: 116 a+1: 188 a+2: 63 a+3: 128

Thank you for every discussion.
